Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a portable computer support
structure and more particularly, to such a portable computer
support structure, which is practical in use to support a portable
computer, enabling the portable computer to be adjusted to the
desired a standing operative angle.
[0003] 2. Description of Related Art
[0004] In order to support a portable computer, for example, a
tablet PC in a standing position for operation, a support structure
may be used to support the portable computer in position.
[0005] However, a conventional portable computer support structure
is simply adapted to support the portable computer in the standing
position, not adjustable to change the standing angle of the
portable computer. Because this design of portable computer support
structure is not adjustable, it does not fit different users of
different body heights. Further, this limitation causes a number of
problems as excessively high or low view angle, reflection of the
light of the display screen, etc., resulting in inconvenience use
of the portable computer.
[0006] Therefore, it is desirable to provide a portable computer
support structure that eliminates the aforesaid drawbacks.
SUMMARY OF THE INVENTION
[0007] The present invention has been accomplished under the
circumstances in view. It is the main object of the present
invention to provide a portable computer support structure, which
can conveniently be controlled to adjust the angle of the tablet PC
supported thereon subject to the user's body height, giving
convenience of use.
[0008] To achieve this and other objects of the present invention,
the portable computer support structure is adapted to support a
portable computer that comprises a supporting portion at the back
side thereof. The portable computer support structure is comprised
of a base member, a support arm, a back-stick plate, a step-less
pivoting device, and a support block.
[0009] The base member comprises a first pivoting structure
disposed at a top surface near the rear side of the base member,
and a second pivoting structure disposed at the top surface in
front of the first pivoting structure. The support arm has a bottom
pivoting portion disposed at the bottom side and locating means
disposed at the top side thereof. The bottom pivoting portion is
fastened pivotally with the first pivoting structure of the base
member for enabling the support arm to be rotated relative to and
lifted from the base member. The back-stick plate has a bottom side
and a top side. The bottom side of the back-stick plate is pivoted
to the second pivoting structure of the base member for enabling
the back-stick plate to be rotated relative to and lifted from the
base member to let the support arm be supported on the top side of
the back-stick plate after lifting of the support arm from the base
member. The step-less pivoting device comprises a base affixed to
the locating means of the support arm, and a step-less shaft
inserted through and rotatable step-lessly relative to the base of
the step-less pivoting device. The support block is adapted to
support the portable computer on the support arm, comprising a
mounting portion fastened to the step-less shaft of the step-less
pivoting device, and a coupling portion connectable to the
supporting portion of the portable computer.
[0010] When in use, the user can freely adjust the angle of
inclination of the portable computer to the best view angle subject
to the user's body height by using the step-less shaft of the
step-less pivoting device, eliminating the problem of reflection of
light of the display screen. And the portable computer can be held
in the desired angular position for convenience of use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] Referring to FIG. 1, a portable computer support structure
in accordance with the present invention is shown comprised of a
base member 1 and a portable computer 6 supportable on the base
member 1. The portable computer 6 according to the present
preferred embodiment is a tablet PC. The base member 1 has a
receiving open chamber 13, which accommodates an input device, for
example, a keyboard 7.
[0017] Referring to FIGS. 2 and 3 and FIG. 1 again, the portable
computer 6 comprises a pair of sliding grooves disposed at the back
surface, forming a supporting portion 61. The portable computer
support structure further comprises a support arm 2, a back-stick
plate 5, a step-less pivoting device 3, and a support block 4.
[0018] The base member 1 has provided at the top surface 10 a first
pivoting structure 11 near the rear side of the base member 1 and a
second pivoting structure 12 in front of the first pivoting
structure 11. The support arm 2 has a bottom pivoting portion 21 at
the bottom side thereof and a recessed locating portion 22 at the
top side thereof. The bottom pivoting portion 21 is fastened
pivotally with the first pivoting structure 11 of the base member 1
for enabling the support arm 2 to be rotated relative to and lifted
from the base member 1. The support arm 2 further comprises two
parallel sliding grooves 23.
[0019] The back-stick plate 5 has the bottom side 51 pivoted to the
second pivoting structure 12 of the base member 1 for enabling the
back-stick plate 5 to be rotated relative to and lifted from the
base member 1, and a top side 52 terminating in a coupling flange
521, which is coupled to and slidable along the sliding grooves 23
of the support arm 2. When lifted the support arm 2 and the
back-stick plate 5 from the base member 1, the coupling between the
sliding grooves 23 and the coupling flange 521 enables the support
arm 2 to be supported on the top side 52 of the back-stick plate
5.
[0020] The step-less pivoting device 3 comprises a base 31 and a
step-less shaft 32. The base 31 is affixed to the recessed locating
portion 22 of the support arm 2. The step-less shaft 32 is inserted
through and rotatable step-lessly relative to the base 31 of the
step-less pivoting device. The support block 4 comprises a mounting
portion 41 fastened to the step-less shaft 32 of the step-less
pivoting device 3, and a pair of sliding rails of L-shaped cross
section forming a coupling portion 42 that is coupled to the
supporting portion 61 of the portable computer 6. After connection
of the supporting portion 61 of the portable computer 6 to the
coupling portion 42 of the support block 4, the portable computer 6
can be rotated with the support block 4 and the step-less shaft 32
relative to the base 31 and the support arm 2 steplessly. The
sliding rails of L-shaped cross section of the coupling portion 42
may be arranged facing each other or reversed to each other.
Alternatively, the sliding rails of the coupling portion 42 can be
made having a T-shaped cross section.
[0021] When in use, the portable computer 6 is coupled to the
support block 4 at the top side of the support arm 2, and rotated
with the support block 4 and the step-less shaft 32 relative to the
base 31 and the support arm 2 to the desired angle of inclination
subject to the user's body height, i.e., the user can freely adjust
the angle of inclination of the portable computer 6 to the best
view angle, eliminating the problem of reflection of light of the
display screen. Therefore, the portable computer 6 can be held in
the desired angular position for convenience of use.
[0022] Referring to FIGS. 4 and 5 and FIG. 1 again, after an use,
the portable computer 6 is removed from the support block 4, and
then the back-stick plate 5 and the support arm 2 are respectively
rotated downwardly inwards and received to the base member 1, and
then the keyboard 7 is received inside the recessed receiving open
chamber 13 of the base member 1. FIG. 5 shows the portable computer
support structure set in the received status.
[0023] Although the present invention has been explained in
relation to its preferred embodiment, it is to be understood that
many other possible modifications and variations can be made
without departing from the spirit and scope of the invention as
hereinafter claimed.
